Results of analysis presented in this paper were based on analysis of casts made especially for this research purpose and related to actual cast – industrial. The evaluation of the dimensional accuracy of casts was made in relation to the pressure of the liquid metal with consideration of the ceramic mould temperature. Ceramic moulds used in these analyses were made from crystalline quartz with an aqueous colloidal silica binder containing polymers (KK), and ethyl silicate (KE).
